I am disappointed with the performance numbers of my boat.
In the spring, on a good day I could hit a top speed of 38-40 MPH.
I know there are a ton of variables (ie. bottom growth) but this decline seems major.
I am suspecting that I slightly bent a propeller blade after running in shallow water, sandy bottom. (Paint is rubbed off very bottom skeg of outboard.)
I get no vibration however.
To my friends here with similar rigs...are these numbers consistent with your experience?
